Application October 15, 1948, Serial no. 54,729

This invention appertainsto the lubrication of machinery and more particularly to oilers or oil cups. I

In one type of oiler, now in general use, the same includes an oil cupor reservoir having a top central filling cap, a discharge fitting and This type of oiler has certain inherent disad- I vantages, namely, (1) there isno way of regulating the flow of oil, as the rate of feed is dependent upon capillary action, the height that the oil must be raised andthe length of the wick in the stand pipe; (2) it is 'difficult and many times impossible to remove'the'wick for cleaning and replacing; (3) the top of the stand pipe is usually very close to the filler cap, thus when the spout of an oil can is inserted for the purpose of filling the reservoir the stand pipe interferes with the easy insertion of the spout of the oil can, and the wick may be damaged or distcrted by the spout; (4) the stand pipe and excessive amount of wicking occupy valuable space; (5) since oil cannot be raised by capillary action much more than a few inches it becomes necessary to adopt exceedingly large diameters of reservoirs and this, of course, creates installation diiiiculties.

It is, therefore, the primary object of this invention to eliminate the disadvantages above recited and to provide an oiler in which the desired rate of flow of oil can be easily governed and one in which the oil is still effectively filtered.

Another salient object of the invention is to provide a wick retainer tube carried by the discharge fitting and provided with outlet ports designed to receive various sizes or densities of wicks, which protrudes directly into the reservoir slightly above the bottom thereof, the size or density of the wick or the diameter of the wick retaining tube governing the rate of flow broken away and in 1 cla m. (or. 184- 87) With these and other objects in view, the invention consists in the-novel construction, arrangement and formation of parts, as will be hereinafter I more specifically described and claimed, and illustrated in the accompanying drawing, in which drawing: 7

Figure 1 is a side elevational view of my improved wick oiler, parts of the view being shown sectionto illustrate structural details. l

Figure 2 is a detail side'elevational view of the novel wick retaining tube.

Figure 3 is a horizontal, sectional view through the wick retaining tube taken on the line 33 of Figure 1, looking in the direction of the arrows. 4 q a Referring to the drawing in detail, wherein similar reference characters designatev corresponding parts throughout the several views, the letter 0 generally indicates my improved wick oiler and the same includes a bottom wall 5, preferably flanged at its periphery, as at 6. for the oil reservoir body 1. The bottom wall 5 of the body can be formed of any preferred F materials and actually constructed in any desired way. The wall 5 is preferably formed from metal and the body is preferably formed from transparent or translucent material such as plastic. The upper end of the body I of the reservoir is provided with a filler cap 8. The axial center of the bottom wall 5 of the reservoir has formed thereon a depending discharge fitting 9, which can be externally threaded for association with the desired machine.

In accordance with my invention, the fitting 9 detachably receives the removable wick retaining tube in. This wick retaining tube I n can be associated with the fitting 9 in any desired way. As illustrated, the fitting 9 is provided with an enlarged axial bore I I, which receives the tube and this bore is slightly restricted as at l2, adjacent to its upper end. Likewise the tube is provided with external threads is and the bore adjacent to the restriction I2, is internally threaded so that the tube can be threaded therein. The tube I ll is substantially cylindrical in shape and its extreme upper end above the threads is slightly reduced in diameter to snugly fit in the restriction bore 12. The lower end of the tube is closed as at l4 and this end is provided with a screw driver slot [5. Restricted outlet ports l6 are formed in the side of the tube and these ports communicate with the interior of the tube.

Detachably fitted within the tube is the desired wick IT. The bottom wall I4 of the tube defines a seat for the wick so that the same cannot fall out.

The retainer tube I is designed so that the wick of any predetermined size or density can be inserted therein. The wick serves a dual purpose, it filters the oil and chiefly acts as a restricting agent for the purpose of governing the rate of oil feed. In this connection, it is to be noted that the shorter the wick or the smaller its diameter, or less its density, the faster the ra e 01' feed will be. Likewise, the greater its density, the longer the wick or the larger its diameter, the slower the rate of feed. Since'the rate of feed in the oiler is obtained by restricting the bore in the removable wick retainer by the use of various sizes of wicks, the same results can be obtained by making removable retainer tubes by merely varying the diameter of the bore. Thus, instead of using one retainer tube with various sizes of wicks, several retainers could be used,,ea,ch with a, diiferent diameter bore.

However, it is proposed to furnish a variety 0! wicks with each oiler and ,to designate the wicks in a distinctivemanner to indicate the rate of flow of each individual wick. To illustrate, onewick could be colored white to indicate very slow feed; another black, to indicate slow feed, a third green, to indicate medium feed, a fourth blue .to indicate fast feed and another red to indicate very fast feed. Obviously, the colorsselected are only arbitrary.

Attention is again directed to the fact that the oiler can be easily filled and that it has a large area of capacity. Obviously, the insertion of. an oil can spout in the oiler will not hurt the wick or the retainer tube In. Thus, a smaller diameter reservoir can be used with a larger ca- 4 pacity than ordinary oilers now on the market, and this permits the free installation of the oilers in confined places. The wick I1 forms an admirable filter and thus clean oil is assured for the machine.

Changes in details may be made without departing from the spirit or the scope of my invention, but what I claim as new is:

In an oiler or the like of the type having a bottom wall provided with a depending discharge fitting having internal and external threads, a. removable wick retainer tube adapted to be threaded into the fitting, said wick retainer tube having a conically shaped closed lower end and an axial bore opening out on the upper end thereof, a wick received in said bore and seated against said closed lower end, said wick being solely supported by said wick retainer tube, said conically shaped closed lower end having a transverse tool receiving slot in the extreme end thereof, whereby the tube and wick can be quickly moved into and out of the discharge fitting, and restricted outlet ports communicating with the axial bore adjacent the conically .shaped closed lower. .end.
